✦ Synopsis

Recent measurements of the magnetoreflection and of the de Haas-van Alphen effect have made possible a more accurate determination of the band parameters of pyrolytic graphite. In principle, these experiments could provide a more direct measurement of the small spin-orbit interaction in graphite. This interaction lifts the degeneracy of the E8 bands everywhere along the zone edge and gives rise to a band gap near point K which could be deduced from analysis of the magnetoreflection experiment. When the degeneracy of the energy bands at point H is lifted, two extremal Fermi surface areas are obtained, thus predicting two low frequency de Haas-van Alphen oscillations.
